Aug 13 - From Cold Pool to Hot Queue: Annotation Curation with FiftyOne Workshop

**[Pre-registration is mandatory to clear building security](https://voxel51.com/events/from-cold-pool-to-hot-queue-annotation-curation-with-fiftyone-august-13-2026)** **Date, Time and Location** Aug 13, 2026 5:30 PM - 8:30 PM ET Microsoft Research Lab – New England (NERD) at MIT Deborah Sampson Conference Room One Memorial Drive, Cambridge, MA In this hands-on workshop, you'll use [FiftyOne](https://docs.voxel51.com/index.html) to run the full rare-class mining loop end-to-end on a large unlabeled image pool: compress the pool with near-duplicate detection, embed images with a modern vision backbone, mine candidate positives via seeded similarity from a tiny labeled set, confirm them through targeted human review, and prioritize the survivors for annotation using representativeness and uniqueness scores. You'll then fine-tune a detector on the prioritized examples and come back to FiftyOne to verify the missed-mode clusters actually got covered. *What You'll Walk Away With* * A working FiftyOne pipeline for finding rare classes in any visual dataset you own * A repeatable four-stage funnel — compress, mine, confirm, prioritize — with a clear objective at each stage * A fine-tuned detector that demonstrably outperforms one trained on the same number of randomly sampled images * The mental model that data curation — not architecture or hyperparameters — is the highest-leverage thing you can do to improve a rare-class detector
